Quilt, Eagle Pattern

this is a quilt with an eagle pattern. I found it on the Metropolitan museum of Art website http://www.metmuseum.org/works_of_art/collection_database/american_decorative_arts/quilt_eagle_pattern/objectview.aspx?page=61&sort=0&sortdir=asc&keyword=&fp=1&dd1=1&dd2=0&vw=1&collID=1&OID=10014424&vT=1

what drew me to this piece was the eagle in the middle with all the various border patterns that surround it. this piece is also symmetrical, which i found to be very cool. there are some elements of line including implied line, in-between the blue zigzag and the beige colored triangles that are more in the center. in-between these two is a blank space, but i feel as if the mind is forcing me to see another set of pattern there, even though there technically isn't.
